Pneumatic Actuator Type PA11/21

Our pneumatic full plastic actuators PA11/21 can serve you in many ways. They are available with or without stroke limiter as well as in the different modes of operation.

Range: PA11 from d16DN10 up to d32DN25 and PA21 from d40DN32 up to d63DN50.

Thanks to the new position indication with integrated NAMUR interface – accessory assembly to our PA11/21 is as easy as it gets.

Naturally the flange interface also corresponds to the NAMUR standard. Therefore third party valves are no problem.

• position feedback
• digital positioner
• connection to AS-i bus system available
• adapter for F04 and F05 interface

Advantages:

• robust PP-GF housing
• full plastic actuator
• position indicator with integrated NAMUR interface
• fast cycle times
• very good price-performance ration for all types
• multi functional modul available with different limit switch types

Pneumatic Actuator Type PA30 to PA90

The pneumatic actuator series PA30- PA90 serves to operate valves with a 90° positioning angle. Georg Fischer actuators already comply with both the EN standards, as well as divers ISO standards: Actuator mounting flange according to ISO 5211; Actuator connection with square according to DIN 3337; Connection for solenoid valve, positioner and limit switch according to VDI/VDE 3845 (NAMUR); Optical position feedback

All GF Piping Systems actuators can be used as open/close or control actuators. The double acting design means that the valve is opened or closed by the actuator applying compressed air. Depending on the requirement, the springs can open or close. The single-acting actuators only apply compressed air on one side, while adjustment on the other side is by spring force. This means that if there is air failure they return automatically to a safety position.

Standard interfaces enable easy configuration of: solenoid valve, limit switch and positioner.

Options:

• position feedback
• digital positioner
• connection to AS-i bus system available

Advantages:

• integrated NAMUR interface
• fast cycle times
• wide torque range, starting at 8 Nm (5.9 lb. ft) up to 3840 Nm (2832 lb. ft)
• very good price-performance ratio for all types
• easy assembly with various limit switch options
• low installation height

Pneumatically Actuated Butterfly Valve Type 240

The Type 240 series pneumatically actuated wafer style butterfly valve from Georg Fischer is the ultimate choice for the high demands of the industrial world. The unique double eccentric design means the disc is not in contact with the seal in the open position. The result is less wear and operating torques that are half that of our previous model. Better chemical compatibility is achieved because the inner body is the same material as the pipe. The unique Q ring design insures a superior seal with virtually any type of flange without the need for additional gaskets. Additionally, the electro-pneumatic positioner, stroke limiter, and feed back switches give flexibility for integration into a wide variety of applications.

Advantages:

• Size range 2” to 12” wafer style
• Available in PVC-U, PVC-C, polypropylene, and PVDF
• Rated for 150 PSI (bidirectional)
• EPDM or FPM seals
• Double eccentric, off-center shaft for reduced wear and lower torque requirements
• Special Q-ring design eliminates the need for flange gaskets

Options:

• Declutchable manual override
• Limit switches
• Electro-pneumatic positioner (4-20mA) or 3-15 PSI
• ASI control

Pneumatically Actuated Butterfly Valve Type 242

The Type 240 series pneumatically actuated lug style butterfly valve from Georg Fischer is the ultimate choice for the high demands of the industrial world. The unique double eccentric design means the disc is not in contact with the seal in the open position. The result is less wear and operating torques that are half that of our previous model. Better chemical compatibility is achieved because the inner body is the same material as the pipe. The unique Q ring design insures a superior seal with virtually any type of flange without the need for additional gaskets. Additionally, the electro-pneumatic positioner, stroke limiter, and feed back switches give flexibility for integration into a wide variety of applications.

Advantages:

• Size range 2” to 8” ANSI lug style
